He teaches Longitudinal Data Analysis, Statistical Consulting, and Sampling Theory among other courses. He is chair of the Leuven Statistics Research Centre (LStat). <br>Prof. Molenberghs obtained his PhD in Statistics in 1993. The title of his research project was “A Full Maximum Likelihood Method for the Analysis of Multivariate Ordered Categorical Data”. His supervisors were Prof. Rousseeuw and Prof. Lesaffre. In 2004, he was appointed full professor at Hasselt University. Three years later, he was appointed part-time professor at KU Leuven. <br>Throughout the years, prof. Molenberghs has been the (co-)advisor for many PhD researchers and master students. He has also been a member of many expert committees and professional societies such as the Royal Statistical Society (UK), the International Society for Clinical Biostatistics and the Psychometric Society. Among other boards, he’s an Advisory Board Member of Biostatistics and the Executive Editor of Biometrics. Lastly, prof. Molenberghs is a consultant for many partners in diverse fields including Pfizer, the Universiteit Antwerpen, and Ziekenhuis Oost Limburg. </div></div><div><h3><strong>Título</strong></h3></div><div><span style="font-variant-numeric:normal;font-variant-east-asian:normal;font-variant-alternates:normal;box-sizing:border-box;color:rgb(33,33,33);font-family:"Open Sans";text-align:justify;font-size:12pt;vertical-align:baseline"><b><span style="font-family:Arial,Helvetica,sans-serif;font-size:small;color:rgb(34,34,34)">The statistical evaluation of surrogate endpoints in clinical trials – and beyond</span> </b></span></div><div><b><br></b></div><div><h3><strong>Resumo</strong></h3></div><div>Both humanitarian and commercial considerations have spurred intensive search for methods to reduce the time and cost required to develop new therapies. The identification and use of surrogate endpoints, i.e. measures that can replace or supplement other endpoints in evaluations of experimental treatments or interventions, is a general strategy that has stimulated much enthusiasm. Surrogate endpoints are useful when they can be measured earlier, more conveniently, or more frequently than the "true" endpoints of primary interest. Regulatory agencies around the globe, particularly in the United States, Europe, and Japan, are introducing provisions and policies relating to the use of surrogate endpoints in registration studies. But how can one establish the adequacy of a surrogate, in the sense that treatment effectiveness on the surrogate will accurately predict treatment effect on the intended, and more important, true outcome? What kind of evidence is needed, and what statistical methods portray that evidence most appropriately? The definition of validity, as well as formal sets of criteria, have been proposed, including use of the proportion explained, jointly the within-treatment partial association of true and surrogate responses, and the treatment effect on the surrogate relative to that on the true outcome. In a multi-centre setting, these quantities can be generalized to individual-level and trial-level measures of surrogacy. Consequently, a meta-analytic framework studying surrogacy at both the trial and individual-patient levels has been proposed. A number of variations of this theme have been developed, depending on the type of endpoint for the true and surrogate endpoint and on the focus of the evaluation exercise. Recent developments have been based on information theory, principal stratification, and causal inference. The field of surrogate marker evaluation, in turn, has sparked a number of developments towards efficient estimation in complex hierarchical models.<div style="text-align:justify"><h1 style="text-align:start;margin:0px;padding:0px;outline:0px;box-sizing:border-box;font-family:Poppins,sans-serif;font-weight:500;line-height:1.6;color:rgba(0,0,0,0.87)"></h1></div></div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><span style="font-size:13px"><font face="arial, sans-serif" color="#000000"><br></font></span></div><div><b>Contamos com a participação de todos! </b></div></div></div></div></div><div><br></div><div>Abraço</div></div><div><br></div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><span style="font-size:13px"><font face="arial, sans-serif" color="#000000">Atenciosamente,</font></span></div><span style="font-size:13px"><font face="arial, sans-serif" color="#000000">Fábio Prataviera</font></span><div style="font-size:13px"><font face="arial, sans-serif" color="#000000">Universidade de São Paulo</font></div><div style="font-size:13px"><font face="arial, sans-serif" color="#000000">Escola Superior de Agricultura "Luiz de Queiroz"</font></div><div style="font-size:13px"><font face="arial, sans-serif" color="#000000">Departamento de Ciências Exatas</font></div><div style="font-size:13px"><font face="arial, sans-serif" color="#000000">Telefone: +55 (19) </font><span style="color:rgb(0,0,0);font-family:arial,sans-serif">3447-8905</span><font face="arial, sans-serif" color="#000000"><br></font></div><div style="font-size:13px"><font face="arial, sans-serif" color="#000000">ORCID: <span style="font-size:small"><a href="https://orcid.org/0000-0001-8190-1086" target="_blank">https://orcid.org/0000-0001-8190-1086</a></span></font></div><div><font face="arial, sans-serif" color="#000000">CV: <a href="http://lattes.cnpq.br/3225385085167748" target="_blank">http://lattes.cnpq.br/3225385085167748</a></font><span style="font-size:small;color:rgb(29,34,40);font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><br></span></div></div></div></div></div>
